Geranium plant named &#39;Fisrocoral&#39;

ABSTRACT

A new and distinct cultivar of geranium plant named ‘Fisrocoral’, as described and illustrated, and particularly characterized by the combined features of deep orange semi-double flowers, large, semi-spherical umbels, medium green foliage with strong zonation, vigorous growth, but well-branched and fairly round plant habit.

BACKGROUND OF THE INVENTION

[0001] The present invention comprises a new and distinct cultivar of geranium, botanically known as Pelargonium zonale, and hereinafter referred to by the cultivar name ‘Fisrocoral’.

[0002] ‘Fisrocoral’ is a product of a planned breeding program which had the objective of creating new geranium varieties with deep salmon to red flower color in combination with vigorous growth and good outdoors performance.

[0003] ‘Fisrocoral’ was originated from a hybridization made by the inventor Angelika Utecht in a controlled breeding program in Galdar, Gran Canaria, Spain, in 1996. The female parent was an unpatented hybrid seedling, no. K92-990-1, derived from a cross between the unpatented cultivar ‘Fisnida’ and the cultivar ‘Volcano’ (U.S. Plant Patent no. 5,940). The hybrid seedling was characterized by red, single-type flowers, large inflorescences, and medium green foliage with strong zonation. ‘Fisnida’ has large inflorescences of orange-red, single-type flowers, medium green foliage with distinct zonation, and fairly vigorous growth, while ‘Volcano’ has red, semi-double flowers, medium green foliage without zonation, and compact plant habit.

[0004] The male parent of ‘Fisrocoral’ was an unpatented seedling, no. 194-1187-15, originated by self-pollinating the commercial variety ‘Isabell’, disclosed in (U.S. Plant Pat. No. 7,080). ‘Isabell’ is characterized by brilliant orange-red, semi-double flowers and medium green foliage with weak zonation.

[0005] ‘Fisrocoral’ was selected as one flowering plant within the progeny of the stated cross by Angelika Utecht in 1997, in a controlled environment in Galdar, Gran Canaria, Spain.

[0006] The first act of asexual reproduction of ‘Fisrocoral’ was accomplished when vegetative cuttings were taken from the initial selection in the fall of 1997, in a controlled environment in Galdar, Gran Canaria, Spain, by, or under the supervision of, Angelika Utecht.

[0007] Horticultural examination of plants grown from cuttings of the plant initiated in May 1998, in Hillscheid, Federal Republic of Germany, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Fisrocoral’ are firmly fixed and are retained through successive generations of asexual reproduction. The new cultivar reproduces true to type.

[0008] ‘Fisrocoral’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length. The following observations, measurements, and comparisons describe plants grown in Hillscheid, Germany, and in Langley, British Columbia, Canada, under greenhouse conditions which approximate those generally used in commercial practice.

BRIEF DESCRIPTION OF THE INVENTION

[0009] The following traits have been repeatedly observed and are determined to be basic characteristics of ‘Fisrocoral’ in combination distinguish this geranium as a new and distinct cultivar:

[0010] 1. brilliant, deep-orange colored, semi-double flowers;

[0011] 2. large, semi-spherically shaped inflorescence, well above the foliage;

[0012] 3. medium-green foliage with strong zonation;

[0013] 4. vigorous growth, and tall, but uniformly rounded, plant habit; and

[0014] 5. medium, mid season spring flowering response.

[0015] Of the many commercial cultivars known to the present inventor, the most similar in comparison to ‘Fisrocoral’ are the patented cultivars ‘Fisgrand’ (U.S. Plant Pat. No. 8,760), and the related cultivars ‘Fismerk’ (U.S. Plant patent application Ser. No. 09/773,010), and ‘Fisfire’ (U.S. Plant patent application Ser. No. 09/772,845).

[0016] In comparison to ‘Fisgrand’, ‘Fisrocoral’ has a somewhat lighter, orange, not orange-red flower color, and larger umbels, stronger zonation on leaves, and even taller, and somewhat more evenly shaped, plant habit.

[0017] In comparison to both ‘Fismerk’ and ‘Fisfire’, ‘Fisrocoral’ a less intense hue of flower color, and distinctly more vigorous growth habit.

BRIEF DESCRIPTION OF THE DRAWING

[0018] The accompanying photographic drawing shows typical flower and foliage characteristics of ‘Fisrocoral’ with colors being as true as possible with an illustration of this type. The drawing shows a flowering pot plant in a 14 cm container.

DETAILED BOTANICAL DESCRIPTION

[0019] In the following description color references are made to The Royal Horticultural Society Colour Chart (RHS). The color values were determined indoors from flowers developed in a green-house in May 2001, in Hillscheid, Germany. The measurements were taken in Langley, British Columbia, Canada in early July, 2001, 18 weeks after planting of rooted cuttings. The plants were growing in 8 inch containers and had not been pinched.
